Her karakter, detaylı ve net bir metin temsili sağlamak için 5x8 pikseldir.

Bu modülün görüntüleme modu 4 satırdır ve her satır 20 karakter gösterebilir. OLED teknolojisinin kendiliğinden ışık yayma özelliği sayesinde, bu modül arka aydınlatma gerektirmez, bu da daha hafif ve ince bir tasarım ile 10.000:1 geliştirilmiş bir kontrast oranı sağlar. Ayrıca, ultra geniş bir görüş açısına (175 dereceye kadar) sahip olup, çeşitli açılardan tutarlı görüntü kalitesi sunar. Modül ayrıca düşük enerji tüketimi ve geniş bir çalışma sıcaklığı aralığı sunarak çok yönlülüğünü gösterir.

WEO002004C'nin çalışma sıcaklığı aralığı -40°C ile +80°C arasındadır, depolama sıcaklığı aralığı ise -40°C ile +85°C'dir. Bu, ekstrem koşullarda stabil performans sağlar. Modül, 2.4V ile 3.3V arasında bir lojik voltaj aralığında çalışır, tipik değer 3V'dir ve 1/32 duty sürüş yöntemi kullanır.

Ayrıca, WEO002004C birden fazla arayüz seçeneğini destekler, bunlar arasında 6800/8080 8-bit paralel ve I2C/SPI seri arayüzler bulunur, farklı sistem gereksinimlerini karşılamak için esnek bağlantı seçenekleri sunar. Modül serisi ayrıca çeşitli müşterek ihtiyaçlara hitap eden çeşitli Esnek Baskılı Devre (FPC) seçenekleri sunar.

Güvenilir görüntü kalitesi, geniş çalışma sıcaklığı aralığı ve esnek arayüz seçenekleri ile SSD1311 sürücü IC'ye sahip WEO002004C OLED Ekran Modülü, geleneksel LCD modüllerine pratik bir alternatif sunar. Ürününüzün görüntüleme performansını artırmak, üstün görüntü kalitesi ve düşük enerji tüketimi sağlamak için bu 20x4 karakterli OLED modülünü değerlendirmenizi öneririz.

AYRINTILAR

Arayüz Pin Fonksiyonlari

Pin No.

Sembol

Pin Type

TANIM

－

No connection

VSL

This is segment voltage (output low level) reference pin.
When external VSL is not used, this pin should be left open.
When external VSL is used, connect with resistor and diode to ground (details depend on application).

VSS

Ground pin. It must be connected to external ground.

REGVDD

Internal VDD regulator selection pin in 5V I/O application mode.
When this pin is pulled HIGH, internal VDD regulator is enabled (5V I/O application).
When this pin is pulled LOW, internal VDD regulator is disabled (Low voltage I/O application).

SHLC

This pin is used to determine the Common output scanning direction.
COM scan direction

SHLC	COM scan direction
1	COM0 to COM31 (Normal)
0	COM31 to COM0 (Reverse)

Note
(1) 0 is connected to VSS
(2) 1 is connected to VDDIO

SHLS

This pin is used to change the mapping between the display data column address and the Segment driver.
SEG scan direction

SHLS	SEG direction
1	SEG0 to SEG99 (Normal)
0	SEG99 to SEG0 (Reverse)

Note
(1) 0 is connected to VSS
(2) 1 is connected to VDDIO

VDD

Power supply for core logic operation.
VDD can be supplied externally or regulated internally.
In LV IO application (internal VDD is disabled), this is a power input pin.
In 5V IO application (internal VDD is enabled), VDD is regulated internally from VDDIO.
A capacitor should be connected between VDD and VSS under all circumstances.

VDDIO

Low voltage power supply and power supply for interface logic level in both Low Voltage I/O and 5V I/O application. It should match with the MCU interface voltage level and must be connected to external source.

BS0

MCU bus interface selection pins. Select appropriate logic setting as described in the following table. BS2, BS1 and BS0 are pin select.
Bus Interface selection

BS[2:0]	Interface
000	Serial Interface
001	Invalid
010	I2C
011	Invalid
100	8-bit 6800 parallel
101	4-bit 6800 parallel
110	8-bit 8080 parallel
111	4-bit 8080 parallel

Note
(1) 0 is connected to VSS
(2) 1 is connected to VDDIO

BS1

BS2

GPIO

I/O

It is a GPIO pin. Details refer to OLED command DCh.

CS#

This pin is the chip select input connecting to the MCU.
The chip is enabled for MCU communication only when CS# is pulled LOW (active LOW).
In I2C mode, this pin must be connected to VSS.

RES#

This pin is reset signal input.
When the pin is pulled LOW, initialization of the chip is executed.
Keep this pin pull HIGH during normal operation.

D/C#

This pin is Data/Command control pin connecting to the MCU.
When the pin is pulled HIGH, the data at D[7:0] will be interpreted as data.
When the pin is pulled LOW, the data at D[7:0] will be transferred to a command register.
In I2C mode, this pin acts as SA0 for slave address selection.
When serial interface is selected, this pin must be connected to VSS.

R/W#(WR#)

This pin is read / write control input pin connecting to the MCU interface.
When 6800 interface mode is selected, this pin will be used as Read/Write (R/W#) selection input. Read mode will be carried out when this pin is pulled HIGH and write mode when LOW.
When 8080 interface mode is selected, this pin will be the Write (WR#) input. Data write operation is initiated when this pin is pulled LOW and the chip is selected.
When serial or I2C interface is selected, this pin must be connected to VSS.

E(RD#)

This pin is MCU interface input.
When 6800 interface mode is selected, this pin will be used as the Enable (E) signal.
Read/write operation is initiated when this pin is pulled HIGH and the chip is selected.
When 8080 interface mode is selected, this pin receives the Read (RD#) signal. Read operation is initiated when this pin is pulled LOW and the chip is selected.
When serial or I2C interface is selected, this pin must be connected to VSS.

I/O

These pins are bi-directional data bus connecting to the MCU data bus.
Unused pins are recommended to tie LOW.
When serial interface mode is selected, D0 will be the serial clock input: SCLK; D1 will be the serial data input: SID and D2 will be the serial data output: SOD.
When I2C mode is selected, D2, D1 should be tied together and serve as SDAout, SDAin in application and D0 is the serial clock input, SCL.

IREF

This pin is the segment output current reference pin.
IREF is supplied externally.
A resistor should be connected between this pin and VSS to maintain current of around 15uA.
